The auto shop is telling me that the rear struts effect front end alignment?

They did work on the front end, tie rods, alignment, new tires ect but the new tires wore out (down to cords) in relatively low mileage (with in a year). Now they say the tires aren't warranteed and the alignment was off due to the back struts being slightly worn. Is this correct?

I don't buy this. If the rear struts were worn, why didn't they mention it when the new prats were put on last year? Rear Strut problems would mainly effect front caster, which is a non-tire wearing angle. Either the tires were poor quality or they did not do the alignment correctly when they put on all those parts. Remember, tire/alignment shops are in the BUSINESS of selling tires, shocks, steering parts etc. That is why I do the diagnosis myself and only have the tire shop do the alignment, which I have to have them do twice, because the first time was inaccurate.
